“Breakthrough: Portraits of Women in Science,” three scientists share stories about India’s first interplanetary mission—a mission to Mars. With limited time and budget to design and launch the satellite—called MOM (for Mars Orbiter Mission)—Seetha Somasundaram, Nandini Harinath, and Minal Rohit spent long hours in the clean room, followed by tense and exciting moments tracking the satellite as it entered Mars’s orbit. Their efforts helped India become the first nation to successfully reach the Red Planet on its first attempt.
